@mike70099 Mike, you cannot write files (from code) in Corvid to disk. Not allowed. But what you can do is this: expose a API with wix-http functions (like “get”) and, when such a request comes in, create this csv-file in memory and hand it over to the calling function. Just make sure you do it in chunks (if many rows to deliver), since there is a 14-seconds time limit on backend functions.
This supposes that the other (calling) server is capable of doing a http-get request and, when rows start coming in, write them to a file.
